Tylosaurus

The Tylosaurus is one of the largest species of mosasaur, a large aquatic reptile related to modern day monitor lizards and snakes. An oversized tylosaur appears in the 2008 movie Turok: Son of Stone, where the creature eats a Plesiosaurus.

The Tylosaurus is massive, being larger than any human and possibly rivaling the Carnotaurus of the movie. It is olive in color and features a massive jaw, lined with bone crushing teeth. The creature also possesses massive flippers, which helped it swim in the deep Lost Land oceans.
